Well, with all that was said in the 2009 movie, aside from mentioning "Admiral Archer" and his dog, who we don't even know if they were referring to Jonathan Archer or another Archer altogether, there was very little to indicate that Enterprise came before the movie.

Yes it was Enterprise's Archer and yes Enterprise existed in both time lines. Bob Orci confirmed this in an interview back when the movie was released and he settled this issue.

Sarek: Is the “Admiral Archer” mentioned in the film intended to be Johnathan Archer from Enterprise? If so, he would be over a hundred years old Does the Enterprise timeline exist in this new reality?

BobOrci: yes, it is Admiral Archer is a reference to the Archer we all know and love, and yes he would be over 100, which is a likely life expectancy in a futuristic space faring race of humans (as depicted by McCoy’s (Deforest Kelley) in THE NEXT GENERATION.
